For the first time this season a Twin Cities beach is shut down due to E. coli.
Hennepin County Health inspectors found high levels of E. coli at Crescent Beach on Lake Minnetonka in the city of Tonka Bay.
Health officials say it's very rare to close a beach this year in the season and three things may be to blame for the closure.
"It could be from the rain event that happened Monday night. It could be from wildlife or it could be from a local storm sewer that drains out close to that beach," said Amanda Buell, Hennepin County Health Inspector.
Health inspectors re-tested the water on Thursday and they're hoping to reopen the beach this weekend.
